Thus He showed me: Behold, the Lord stood on a wall made with a plumb line, with a plumb line in His hand. And the LORD said to me, “Amos, what do you see?”
And I said, “A plumb line.”
Then the Lord said: “Behold, I am setting a plumb line in the midst of My people Israel;
I will not pass by them anymore.” Amos 7:7-8

Back when the big satellite dishes were popular I began to study and learn how the technology worked.
I then became able to replace parts, realign, fine-tune, or move the dish to a better, more convenient location.
I remember one day a man called me and wanted me to look at his dish.
He had bought a new receiver but the picture just wasn’t the best.
I went to his house, programmed his receiver, realigned the dish, and he was very satisfied.
I also charged him $100.
He didn’t seem to mind at all.
I suppose he was really pleased with the improvement because it was just a few days later a neighbor of his wanted me to help with their dish.
However they wanted it to be a cheap as I could get it so they said they would do most of the manual labor.
When I arrived to align it, the dish would spin around.
Come to find out they had dug a post-hole and just set the pipe in it and tamped the dirt.
I told them that the dish needed to be in concrete and straight up and down.
A few days later they called and I returned.
The dish was in concrete and solid as a rock but I couldn’t get it to line up for all the satellites, only for 2 or 3 at most.
I stuck my level on the dish and that told me it was leaning.
When I told the man about it, he told me that he “eye-balled it” best he could and it looked pretty up and down to him.
I told him it needed to be straight up and down.
“How was I supposed to do that?” he asked.
“Use a level!” I replied.
“But I didn’t have a level. What was I suppose to do? Go and buy one?”

Now I realize that I was pretty judgmental on the fellow.
I should have never required him to set the pole in concrete or try and make it straight up and down.
Once he did, I should not have said that he needed to use a level to insure that the pole was perpendicular to the ground. (I probably should not have used the word perpendicular this morning. It makes me sound too hoidy-toidy!)
I certainly should have not charged his “happy neighbor” a hundred dollars, which was considerably cheaper than a dealer making a house call; but that’s irrelevant..
It’s probably my fault that I got into the business of satellite dishes to begin with.
And it was my fault that I couldn’t make a leaning dish work because when I left it would only track 3 satellites.
What I should have done was told him to just dig a hole, put the dish in the hole, and point it at the sky. Then go inside and enjoy the TV.
But that would have been a lie!
There is such a thing as what is right and what is wrong.
